Well, I know it's a little passe, but I've been using reiserfs for about 4 years and love it. The recovery is great ! And I've never had it totally go belly up on me !
Same here. Reiser all the way. ext4 performance may be finally getting close to reiser but btrfs is just too new still. And I'm not just talking about a few personal machines or a few servers or a few terabytes or a few users, and more than 4 years. Hundreds of interactive concurrent random-access database users all day every day, about a terabyte of data per server, some with 5 or 10 terabytes and multiple servers in vm's all on one big reiserfs, big backup servers that collect a copy of all the other servers. Some servers running for several years without a reboot. (I even kept one running and hooked to the net even while I transferred it across the data center room to another rack. Triple power supplies means you can unplug one power cord at a time to transfer to a long extension cord from the other rack, then transfer from the extension cord to the pdu in the rack when you get there, without ever losing power along the way ;) Others running for several years without any fs corruption or reinstalls. A few have crashed due to hardware, software, and dos attacks. A few had hardware/ram/heat problems where they would crash as often as once a day for a while until it got fixed. So far I was always good after the reboot and fsck. I have lost fs's due to raid failures. About equally often on hardware vs software raid. With software raid I was more likely to be able to recover the array although it was harder and required me to figure things out that aren't documented too well. If you need snapshots I guess you just have to take your chances. I wish zfs were stable personally. --------------- Welcome to SUSE LINUX 10.0 (i586) - Kernel 2.6.13-15.18-bigsmp (13). foo:~ # uptime 1:59pm up 1421 days 13:14, 43 users, load average: 0.42, 0.52, 0.53 foo:~ # mount /dev/sda2 on / type reiserfs (rw,noatime,acl,user_xattr) --------------- That box was installed March 2006 so it's been in use for 6.4 years and 3.9 years on the current boot. (The data and everything is all on /) Reiserfs has only been debugged since several years ago, no new features = no new bugs. 2 things though: Reiser3 (reiser4 was never finished) outperformed everything that was stable enough to trust, for a long time, but I can't say if if ext4 might possibly have caught up or passed it by now. I can't say if ssd's change the equation. ext4 may have ssd optimizations that matter, or maybe reiser still wins even on ssd's or maybe wins if manually configured just the right way etc. -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
